<p>Provided is a branching filter having small sizes and high performance. A branching filter (30) is provided with (a) a transmission filter (32) which includes piezoelectric thin film resonators (51- 57), and (b) a reception filter (34) which includes piezoelectric thin film resonators (58-60) and an elastic wave resonator. The piezoelectric thin film resonators (51-57) of the transmission filter (32), and the piezoelectric thin film resonators (58-60) and the elastic wave resonator of the reception filter (34) are formed on the same substrate.</p>
